[ Upstream commit b9eff9732cb0f86a68c9d1592a98ceab47c01e95 ]

Component has "card_aux_list" which is added/deled in bind/unbind aux dev
function (A), and used in for_each_card_auxs() loop (B).

static void soc_unbind_aux_dev(...)
{
...
for_each_card_auxs_safe(...) {
...
(A) list_del(&component->card_aux_list);
} ^^^^^^^^^^^^^
}

static int soc_bind_aux_dev(...)
{
...
for_each_card_pre_auxs(...) {
...
(A) list_add(&component->card_aux_list, ...);
} ^^^^^^^^^^^^^
...
}

#define for_each_card_auxs(card, component) \
(B) list_for_each_entry(component, ..., card_aux_list)
^^^^^^^^^^^^^

But it has been used without calling INIT_LIST_HEAD().

> git grep card_aux_list sound/soc
sound/soc/soc-core.c: list_del(&component->card_aux_list);
sound/soc/soc-core.c: list_add(&component->card_aux_list, ...);

call missing INIT_LIST_HEAD() for it.
